Looking for a simple Customer Management tool that integrates well with google workspace

I'm looking for a simple tool that when a customer calls my business, I can input all of their info. I would also like to be able to easily schedule appointments with them in my business google calendar. I also need to be able to have some sort of admin control so I can add my employees so they can input customers that they speak with and follow up with.

What Tools/Software do you recommend?
